                <link>https://jira.mongodb.org/browse/SERVER-52759</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This ticket is for the following work:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Theoretically prove that &lt;tt&gt;moveChunk&lt;/tt&gt; and concurrent DDL cannot run at the same time and either crash or leave garbage (the collection distributed lock plus the &lt;tt&gt;allowMigration&lt;/tt&gt; fields should ensure that)&lt;/li&gt;
	&lt;li&gt;Enable the balancer and auto-splitter in the DDL FSM workloads&lt;/li&gt;
&lt;/ul&gt;
